3D Particle Track plotting.

This figure shows a plot of particle tracks in a reactor from an MCNP run. Every
detail in this figure is generated from a particle track. The outline of the
core at the bottom of the plot was generated by plotting the surface crossings
and projecting them on a 2D plane. The remaining tracks, represent individual
particle paths. In this plot, the axial dimension is energy. Thus as you look at
the outer regions of the reactor, the particle paths go further down since these
particles lose energy in the reflector region of the reactor. The different
colors represent different particle tracks.
Also shown in this plot is the particle biasing. In this case, the
particles are being biased toward a test assembly near the center of the
reactor. The reactor modeled here is the Fast Flux Test Facility and the
test assembly is a Materials Open Test Assembly.

This figure shows a plot of particle tracks in a glovebox. Every detail in this
figure is generated from a particle track. The source objects inside the
glovebox are shown in light green. The sides of the glovebox and the floor are
shown in blue. The tally spheres are shown in red. This plot was generated by
plotting the coordinates of all the surface and tally crossings and then
projecting them in three dimensional grid. Notice that locations that have more
color indicate more particle tracks. Thus it can be seen that the highest dose
rate will be to the large tally sphere closest to the viewer.
